Need someone to set up a system that measuring the time of wearing a brace using a sensor and pay for this

I would like someone to construct or set up a system  that measures the time that someone is wearing a brace. Usually they use temperature or  resistance sensor using a data logger. Please if someone can build this I could pay him.thank you

help: LED dimming via light sensor

I have been unsuccessful in finding a way to duplicate a "screen" with LED lights. where LEDs act like pixels.. whether a 10x10 layout or much more. and each of those LEDs have variable values of brightness. so thats the output... the input would ideally be video but i think im getting ahead of myself, so what about variable light sensors.. so if each sensor was attached to an LED, and if the sensor saw saw 50% brightness the LED would put out 50% brightness, dark sensor equals dark LED and bright light on the sensor meant bright output from the LED and as much in between as possible. any thoughts, opinions or suggestions? thanks, john.

Motion Sensor Toilet paper Dispenser project

I have a project for school where i have to create a motion sensor toilet tissue dispenser kind of like a tiny paper towel dispenser i could put on a counter. I dont know anything about how motion sensors work or how i would make it work. I just need to figure out the price it would be to set up the motion sensors, gears and everything. Any help, such as links to parts or anything that would give me a better understanding of how to set up motion sensors and connecting them to gears and such, would be appreciated.

different liquid detection sensor

I am building a biodiesel production system. at different points in the process, a tank will have different liquids in it (sometimes more than 1 type, separated out). for instance, there is a point where glycerol sinks to the bottom, while biodiesel floats on top. what i want to do is drain the glycerol from the bottom of the tank (via electronically controlled solenoid valve), then when a sensor detects a change in material (biodiesel), shuts off that valve and opens another (final product tank). for the life of me, i cannot find a sensor that will do this for less than $100. preferably, i'd like to spend less than $30. i can work with a resistive type or voltage type sensor. i just need to be able to make that distinction of material change... any ideas? THANKS!!!

Touch sensor connected to magnetic lock

Hi everybody, I would like to know if anyone can help me for this idea. Indeed, I would like to create a touch sensor which will be connected to a magnet system. To be more accurate, the idea involve the same process as a touch screen phone where one needs to do a pattern with 4 touch sensitive cases . The pattern would create and electrical impulse, which would unlock the box by detaching the magnet. So in a nutshell I will need a touch sensors pattern programing that would send an electrical impulse to detached the 2 magnets. I need this system so it could help me for my 1st creation. It needs to be very small to fit in a box of altoids candy for example. As I said, as a 1st creation I am completely lost for all theses "programmation" skills required. Thank you for your help.

Tactiontape - Touch Sensitive Tape for Rapid Prototyping

Hi everyone, Tactiontape is a one-dimensional touch sensor that curves. It's designed to make building interactive physical prototypes easier, even ones with non-planar or complex surface geometry. It functions as a flexible potentiometer and uses a strip of graphite to express a linearly resistive electrical signal, one that corresponds to how far along the tape you've touched. Each sensor is hand-made using materials from an art supply store. Here's a demo: http://www.youtube.com/watch?v=0ggYn70TpZY For purchasing, photos, and more detail: http://www.etsy.com/listing/87989636/tactiontape-curved-touch-sensors-for

Movement sensor to trigger an electric motor - supercheap!

Hello Any electronics whizzes out there? I want to develop a kids toy that reacts when a child moves within a certain range of it. (Remember that game "Grandmothers Footsteps" where you have to creep up on somone but become motionless when they turn around - if you're caught moving you're out.) The sensor and the circuitry (and some moving parts) need to be able to fit inside something the size of a pint glass, run off batteries and preferrably be drawing no current when no-one is in range. Please - if you have some ideas on this drop me a line and I'll explain further. thanks for looking this far! Julius (London, UK)

Proximity key fob for motorcycle

Hey guys, I am working on a custom barebones motorcycle. I want to make the starting system incredibly simple by just carrying a keycard or fob that can be sensed within 4-5 feet of the bike which would allow me to just kick start it and go. I worked in access control before and to my knowledge the cards and fobs needed to be placed basically on top of a sensor to activate it, is there any way to give in just a touch more range? so just having it in my pocket would close the circuit and allow me to kick start the bike? wiring it in isn't a problem, I just need a switch that would sense a fob 4-5 feet away and close a switch. thanks!

motion activated alarm, sort of

RIR Sensor with ~3ft detection capability?

Question for you sensor experts... I'm looking to do a project that would involve detecting when an item passes through a doorway near ground level (~6 inches above ground level).  Doing a bit of research it looks like a reflective infrared sensor would do the trick ... only issue I have come across is that there seem to be a slew of these sensors with detection capability of about 15mm max and then another class of these (home security grade) that have detection capability for several 10's of feet. Any ideas on a RIR sensor (links appreciated!) that has capability ~2-3 feet?  Another caveat is I'd like to string up multiple of these sensors in a close proximity, each with the sensor observing a 2-3 ft area right in front of it. Thanks! Nick

Arduino and proper proximity sensor

Hi guys. I want to use a proximity sensor and an arduino to know when a person is in the shower. What I have in mind if that if the sensor measures a range of distance it would mean that the person is in the shower. I have made some research and the infrared Sharp GP2Y0A21YK0F seems appropriate for the distance range I need that is around 20-60 cm depending on the size of the shower. However I am ignorant in this topic and I want to know if the water from the shower will make an interference when measuring the distance and generally speaking if this is a suitable sensor for my objective. additionally I read that the voltage output from this type of sensor is not linear, would it be difficult to actually know the distance? Many thanks in advance :)

Hidden Proximity Sensor

Hey guys, I am trying to find a method of creating a hidden proximity sensor that would work similarly to a laser i.e. if the line of sight is broken then an output can be achieved, but without actually using lasers. There are a few problems, the sensor will be in a dark space and will have some smoke blown through the line of sight (lasers would be seen). I want the sensors to be hidden, so they will have to be mounted out of sight, but as they will be used in a relatively open space, i imagine this will mean on the ceiling. This will mean that they will have to detect all the way to the floor, so the range will probably have to be at least 8 feet. Does anybody have any ideas? i'd really appreciate any input. Neal
